High RPM at start/ surges
My 2000 dodge durango recently started reving up to a little over 2000 rpm when first started or on cold starts. Occasionally it will surge up and down a bit. After it starts it idles back down to 600. Engine is 4.7 magnum 43,000 miles. Any suggestions.

Might be the throttle position sensor.

Re: High RPM at start/ surges
wouldn't the TPS cause problems all the time? Is there a cold start valve or switch on the 4.7? Perhaps it is causing the engine to run up so high on a cold start. No check engine light is set no driveability problems.
